Innovation and You


Product Hero


Intuitive Operation

The Philips Sonicare DiamondClean Connected Toothbrush works closely with the Sonicare app* on your mobile device, so you can take the guesswork out and get real-time feedback for optimising your brushing techniques.


Comprehensive Oral Care

Featuring 5 modes (including TongueCare+ and Deep Clean+) and 3 intensities (high, medium, low), the Sonicare DiamondClean Connected toothbrush has the flexibility to address various cleaning needs.


Smart Sensor Technology

This Philips Sonicare DiamondClean Connected Toothbrush is integrated with a pressure sensor, so you’ll know when you’re brushing too hard. Additionally, it has a 3D mouth map which highlights trouble areas inside your mouth.


Charge and Go

For convenient organisation and recharging, the Philips Sonicare DiamondClean Electric Toothbrush has a glass holder and a deluxe travel case that can both function as a charger. The spare brush heads also get their own glass case for hygienic storage.
